2 Commits • 2 Features
May 1, 2026May 2026 highlights focused on UI simplification and build-system modernization for Sofie Core. Delivered two key changes: (1) Removed the rundown layout header from the Sofie Core UI to streamline user experience, (2) Enabled rspack for Meteor to support ES modules and improve build performance. These changes reduce UI clutter, accelerate startup/build times, and establish groundwork for future ES module adoption. No user-facing bugs were introduced this month; a build-related fix ensured Sofie launches reliably with ES modules. Technologies demonstrated include rspack, Meteor, ES modules, and PR-driven collaboration.

Feb 1, 2026February 2026 (bbc/sofie-core) monthly delivery summary focusing on business value and technical achievements. Key features delivered: - Documentation publishing workflow improvements: added a custom Meteor setup action and lint-before-build to strengthen CI reliability and ensure consistent docs publishing. - Adlib actions data retrieval enhancement: expanded query projections to include all necessary data for correct adlib action execution. - Playout timeline and persistent state enhancements: introduced OnAir-only timeline object restrictions and exposed a persistent playout state on the LSG to improve playout control and blueprint state management. - UI iconography refresh: replaced nrk-coreicons with FontAwesome for visual consistency and easier maintainability. - Code quality and developer tooling modernization: unified ESLint configuration, refactored components to hooks, and upgraded development templates/tools to reduce duplication and improve developer experience. Major bugs fixed: - Fixed missed projection values when executing adlib actions (data retrieval bug fix) (#1648). - Updated React Lottie library to address compatibility and stability issues (#1659). - Reduced duplication in useOverrideOpHelper for simple objects (#1619). - Docs publishing flow instability fixes to enhance reliability (#1640). Overall impact and accomplishments: - Significantly improved reliability of documentation publishing, adlib execution, and playout scheduling, contributing to reduced operational risk and faster deployment cycles. - Strengthened developer experience and onboarding through tooling consolidation and hook-based refactors. - Delivered measurable improvements in UI consistency and playout control, supporting more predictable show behavior and faster troubleshootability. Technologies/skills demonstrated: - ESLint consolidation and hooks-based React refactors; modernized tooling and templates. - Meteor-based automation support for docs publishing. - FontAwesome integration for UI consistency; advanced playout domain concepts (OnAir, Hold, LSG) and persistent state handling. - Data projection handling and query optimization for adlib actions.
